COMPARISON OF SELECTED HEMATOLOGICAL PARAMETERS IN SEPTEMBER-LAMBING AND FEBRUARY-LAMBING OF SLOVAK MERINO SHEEP

Selected parameters of red and white blood components were observed in September-and February-lambing of Slovak Merino sheep. Blood was samp led from the jugular vein on the following days postpartum: 1, 4, 7, 1 4, 17, 21, 25 and 34. Significant differences were found at the determ ined intervals in which parameters of the red blood component (hemoglo bin, hematocrit, erythrocytes) were evaluated. Total leukocyte counts increased (P < 0.05) on day 21 after parturition in the group of Septe mber-lambing sheep. Similar differences in eosinophil granulocytes wer e observed on day 34 (P < 0.05). This study presents the laboratory re sults of hematological parameters in September-and February-lambing Sl ovak Merino sheep. Significant differences in selected hematological p arameters during the observed period are due to seasonal factors. The results of white and red blood components are an important part of the homeostasy control in animal organisms in the puerperal period. (C) 1 997 Elsevier Science B.V.
